In this article, we will use PHP and the Fpdf library to create a PDF file. We will write code to add text, images, and tables to PDF files so that we can better understand how to generate PDF files. In addition, we will also learn how to use styles and colors to make PDF files more beautiful and readable.

2. Install the required tools

Before you start writing PHP code, you need to make sure that you have installed PHP and the Fpdf library. If the PHP or Fpdf library is not already installed on your system, you can follow the steps below to install it.

Install PHP:

1. Open a terminal in the Linux system and execute the following command:

##sudo apt-get install php

(If you are in other operating systems, please refer to the installation guide for more information)

Install the FPDF library:

Go to the Fpdf official website ( http://www.fpdf.org) and download the latest version of the Fpdf library
1. Unzip the zip package and move the folder to your working directory

NOTE: You need Rename the folder to "fpdf" and make sure it is placed in the correct directory.

Understanding the Fpdf library

Before we start generating PDF files, let us take some time to understand the Fpdf library. The Fpdf library is an open source PDF generation library for the PHP programming language. It can help us create PDF files with various formats, such as text, images, tables, and more.

The Fpdf library also supports the use of various fonts and colors, and can insert hyperlinks and bookmarks as needed. By using the Fpdf library, you can easily generate professional PDF documents without much programming skills.

Create a PDF file

First, we need to create a blank PDF file. In the Fpdf library we can accomplish this using the following code.

<?php
 require('fpdf/fpdf.php');
 $pdf = new FPDF();
 $pdf->AddPage();
 $pdf->Output();
 ?>

In the above code, we create an object named "pdf" and call the "AddPage" method to add a new page. Use the "Output" method to save the PDF file to the server.

Add text to PDF files

Adding text to PDF files is a very simple thing. You can use the following code to achieve this.

<?php
 require('fpdf/fpdf.php');
 $pdf = new FPDF();
 $pdf->AddPage();
 $pdf->SetFont('Arial','B',16);
 $pdf->Cell(40,10,'PDF Tutorial');
 $pdf->Output();
 ?>

In the above code, we use the "SetFont" method to set the font, size and style. After this, we use the "Cell" method to add text to the PDF file.

Add images to PDF files

Adding images to PDF files is also an easy task. Here is a sample code:

<?php
require('fpdf/fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'PDF Tutorial');
$pdf->Image('image.jpg',10,40);
$pdf->Output();
?>

In the above code, we use the "Image" method to add an image and specify the file name, x and y coordinates of the image.

Add tables to PDF files

Adding tables to PDF files is also very simple. The following is a sample code:

<?php
 require('fpdf/fpdf.php');
 $pdf = new FPDF();
 $pdf->AddPage();
 $pdf->SetFont('Arial','B',16);
 $pdf->Cell(40,10,'PDF Tutorial');
 $pdf->Ln(20);
 $pdf->SetFont('Arial','B',12);
 $pdf->Cell(40,10,'Name',1);
 $pdf->Cell(40,10,'Age',1);
 $pdf->Ln();
 $pdf->SetFont('Arial','',12);
 $pdf->Cell(40,10,'John',1);
 $pdf->Cell(40,10,'27',1);
 $pdf->Ln();
 $pdf->Cell(40,10,'Mike',1);
 $pdf->Cell(40,10,'30',1);
 $pdf->Output();
 ?>

In the above code, we use the "Cell" method to add the title of the table, set the table's border style, set the width and height of the table columns, and use the "Ln" method Create a blank line. Using the same method, we can add all necessary rows and columns to the table.

Using styles and colors

The Fpdf library also supports using styles and colors to create PDF files. Here is a sample code:

<?php
 require('fpdf/fpdf.php');
 $pdf = new FPDF();
 $pdf->AddPage();
 $pdf->SetFont('Arial','B',16);
 $pdf->SetFillColor(255,0,0); //设置填充颜色
 $pdf->SetTextColor(255); //设置文本颜色
 $pdf->Cell(40,10,'PDF Tutorial',1,0,'C',true);
 $pdf->Output();
 ?>

In the above code, we use the "SetFillColor" method to set the fill color and the "SetTextColor" method to set the text color. We can also set borders, text size, text position and padding using the "Cell" method.
